Hi All, So I've had my tank running since September 2016 (nearly a year!). This will sound crazy, but it's still fishless. It's a 45 gallon planted aquarium and I did a fishless cycle with ammonia. I did the 24 hour test and completed the cycling process. Eventually, I got some neons. Unfortunately, they were sick (I should have known since they were on sale at the pet store) and they died in two weeks. After that, I kinda lost my motivation. The tank has been running, I've been doing water changes and putting in Seachem fertilizers (Excel, Potassium, Phosphorus, Iron, Flourish), but I stopped putting in ammonia. My question is, does my filter still contain the beneficial bacteria? It's been a while, but they definitely developed. Please let me know your thoughts.
